BIB OR FAUCET.

Application filed May 17,

This invention relates to an improved bib or faucet particularly adapted for use with containers from which liquid is required to be drawn from time to time.

The object of the invention is to provide a bib or faucet which will be relatively small in size and hence economical to manufacture', while permitting the flow of liquid at the same rate as with the larger faucets that are commonly employed, which will effectively prevent leakage when closed, and which may be operated with facility.

The invention consists generally in novel details of structure and combination which will be set forth at length as the description proceeds.

Embodiments of the invention are illustrated in -the accompanying drawings, wherein: v Figure 1 is a longitudlnal sectlonal view of a bib or faucet embodying my improvements.

Figure 2 is a cross sectional view on the line 22 of Figure 1.

Figure 3 is an end elevation of the valve element.

Figure 4 is a side elevation of the valve element. V

Figure 5 is a detail sectional view showing more particularly the arrangement of a ball employed as a guide and detent element. I

Figure 6 is a similar view showing a modified construction wherein a pin is employed as a guide and detent element.

Figure 7 is a fragmentary longitudinal sectional view of a further modified construction.

Figure 8 is a cross section on the line 8-8 of Figure 7.

Figure 9 is an elevation of the guide and detent embodied in the construction of Figure 7.

Figure 10 is an end elevation showing a further modified construction.

Figure 11 is a fragmentary side elevation thereof.

Referring to Figures 1 to 5:

The faucet comprises a tubular body 1 adapted by means of a threaded extension 2 50 to be fitted to a wall of the liquid container and having adjacent its end remote from the extension 2 a discharge spout 3 which extends at an angle to the body 1. At its outer end the body 1 is closed by a valve lug 4 5 which is inserted co-axially in said bo y and 1924. Serial No. 714,020.

is rotatably mounted. The plug 4 extends across the passage of the spout 3 and is preferably of slightly tapering form, the adjacent part of the body 1 bein conformably tapering whereby the plug 4 as a snug fit in said body. The plug 4 is wholly cut away on one side as shown at 5 to provide a large clearance by which communication may be established between the interior of the body 1 and the passage of the spout 3. In its closed position the solid portion of the plug 4 extends across the spout 3 and provides a complete closure therefor. In the fully open position of said plu the wall of the cutaway portion square y overhangs the spout 3, as shown by broken lines in Figure 1, whereby an unobstructed passage of relatlvely large volume is afforded through which liquid may flow freely from the body 1 to the spout 3.

The plug 4 is formed beyond the clearance or cutaway portion 5'with a bearing portion 6 of annular cross section which carries a suitable finger piece 7 by which the plug may be turned.

The plug isheld against endwise displacement from the body 1 by a key 8 which is preferably in the form of a ball and lies partly in a seat provided therefor in the body 1 and partly in a groove 9 formed in the bearing portion 6 of the plug. The groove 9 is slightly more than a half circle in extent and is preferably arranged at a slight inclination to the minor axis of the bearing portion, thereby in co-operation with the key 8 functioning as a coarse thread. As thus formed the groove 9 by its co-operation with the key 8 serves two purposes: First, at its ends it co-operates with said key as a detent to limit theturning movement of the plug 4 whereby the plug may not be moved from its fully open or its fully closed position by a continuanceof effort in the same direction required for the movement of the plug to fully open or fully closed positions and second, it regulates the position of the plug with reference to the conforming tapering face of the bore of the body 1, compelling the close engagement of the plug with such face when the plug is turned to closed position and backing the plug slightly away from such face when the charge flow of the liquid is assured and by preventin the movement of the plug be yond its fully closed sition loss or waste of the liquid is avoi ed. By forcing the lug against the conforming tapering surace of the body 1 when the plug is moved to Elosed position the tight closure of the plu is assured and thereby leakagfi is entire y prevented and b forcing t e plug slightly away from sai conforming tapering surface when the plug is moved to open position facility of opening movement is as sured, regardless of the tightness of fit between the plu and said conforming ta ring surface w on the plug is closed. he degree to which the plug when being moved to open position is forced away from the conforming surface of the body 1 is merely sufiicient to ensure ease of movement but is insuflicient to permit any appreciable leakage past the end of the plug when the same is opened.

By arranging the plug as an end closure for the body 1 and by wholly cutting away one side of the plug to provide a discharge clearance it is possible to make the body 1 of comparatively small diameter without reducing the rate of flow of the liquid and in this way a substantial economy in manufacture is obtained.

Where the key 8 is in the form of a ball said key may be introduced into position through an opening 15 in the wall of the body 1 and the material of said wall adjacent said opening thereafter upset to provide a seat for the ball, as shown more particularly at 16, in Figure 5. Instead of using a ball as the key connection between the body 1 and the plug 4 a pin 8 may be employed, as shown in Figure (3, the pin being fitted in an opening in the body 1 flush With the outer side thereof and projecting at its inner end into the groove 9.

Referring to Figures 7, 8 and 9:

In this case the key connection between the body 1 and the plug 4, indicated at 8*, is formed as an inturned extension of a split resilient ring 10 which is fitted in an annular groove 11 provided in the outer surface of the body 1 adjacent the outer end thereof, the ke 8 projecting through an opening in sai body into the groove 9. The construction is otherwise similar to that above described. This modified construction permits of ready removal of the ping 4 from the body 1, should such removal ound necessary or desirable. For this purpose it is merely required to disengage the projection 8 from the opening in the body 1 whereupon the lug 4 may be moved in the endwise direction from said body.

Referring to Figures 10 and 11:

In some cases to avoid loss or theft of the liquid it may be found desirable to lock the plug 4 in closed position and the modification shown in these figures is constructed with this end in view.

Thus the body 1 is provided at its outer end with a laterally projecting lug 12 and the plug is provided with a finger piece in the form 0 a laterally projecting arm 7 which is formed with an aperture 13 to receive the shackle of a pad lock 14. In the closed position of the plug as assumed by Figures 10 and 11 the opening 13 is so located with respect to the lug 12 that the shackle of a ad lock fitted in said opening will engage t e lug 12 as a stop or abutment to prevent a movement of the plug to open position.

Having fully described my invention, I

claim:

A faucet comprising a bod having a longitudinal bore extending the full length thereof, the rear part of said bore forming a main passage which has an-inletat its rear end, and the front part having the form of an inwardly tapering conical seat which is in axial alinement with said rear part and having its large outer end flush with the front end of the body, and said body having a lateral outlet port extending through said seat; an inwardly tapering conical rotary plug insert-able into said seat from the front end of said body and provided at its outer end with means for turning the same, and having its periphery constructed to form a solid wall and a clearance on diametrically opposite sides thereof whereby the solid wall of the plug in one rotary position of the same will close said outlet port and the clearance of the plug in another position of the same will uncover said port; and means for preventing complete withdrawal of said plug but causing the same to be tightened when turned into a position for closin said outlet port and loosened when the p ug is turned into a position for uncoverin said outlet, said means com rising a helical groove in the periphery o the lug, and an internal proj ction in the b0 y engaging with said groove.
